OREANDA-NEWS A study published in Nature Geoscience showed a wide regional change, with parts of Scandinavia, the USA, Canada, and Russia having a particularly high frequency of these disturbances. Mapping the causes of tree deaths is important because it helps scientists understand how the global carbon stocks in forests are affected by these disturbances and the frequency with which they occur. Researchers estimated a typical time interval between major disturbance events in the world's forests.

The team then used a computational model to calculate the effect of these events on tree mortality, measured as the amount of carbon stored in dead tree wood, and found that they accounted for 12% of total tree mortality. Their modeling showed how even small changes in the frequency of large-scale disturbances can have a significant impact on carbon stocks in forests in 44% of the world's thickest forests.

The model will allow scientists to understand the context of events such as recent forest fires that devastated parts of the Arctic. Fires in the Arctic may simply be an anomaly, or they may be a sign that riots in this region are becoming more frequent compared to historical norm. Currently, additional work is required to study the causes of death of the remaining 88% of the trees in the world in order to calculate the contribution of factors such as competition, drought and extinction of old trees.
